LOCKING-FAUCET.

Specification of Letters Patent.

Application filed July 13, 1909.

Patented May 24, 1910.

Serial No. 507,386.

To all whom 'it may concern:

Be it known that I, JOSEPH S. ERrosoN, citizen of the United States,residing at Burbank, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements inLooking- Faucets, of which the following is a specification.

My invention relates to faucets and particularly those faucets whereinmeans are provided for locking the faucet in either its open or itsclosed position and preventing the actuation of the faucet except bymeans of a key, this particular class of faucet being designed withreference to tank wagons, but not necessarily confined to this use.

The invention includes in general terms, a faucet body having therein avalve, a lever pivoted on the faucet body and connected to the valve toopen or close the same, a locking device on the lever engaging with thefaucet body and preventing a movement of the lever after it has been setin one or the other position and a key adapted to withdraw the catch andpermit the movement of the lever by actuation of the internal valve.

My improved invention is shown in the accompanying drawings, wherein:

Figure 1 is a side view, partly sectional, of a faucet constructed inaccordance with my invention; Fig. 2 is a top view thereof, theactuating lever being in section; Fig. 3 is a vertical transversesection of the faucet taken just forward of the actuating lever; Fig. 4is a detail enlarged section of the upper end of the actuating lever,and Fig. 5 is a perspective view of the key.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters. 7

Referring to these figures, A designates a faucet body of any usualconstruction and which is usually made of brass or other metal. Thisbody is formed in two portions, a rear portion 2 and a mouth portion 3.The part 3 is screw threaded into the rear portion 2 and the rearportion is screw threaded for engagement with the tank, pipe or otherreceptacle. The rear end of portion 3 is beveled, as at 4., to form avalve seat while the portion 2 is provided with the transverse bar 5perforated at its middle to provide a bearing for a longitudinallymovable valve spindle 6 which extends through the bar 5 and at its otherend extends through the forward end of the faucet body, preferablythrough a stuffing box 9 which prevents the escape of oil around thevalve stem. A valve 7 is carried upon the spindle 3 which has a bevelface adapted to, close against the bevel face seat 4. A spring 8 acts tonormally hold the valve in place against the seat. Under ordinaryconditions and when there is considerable pressure of liquid behind thevalve, this pressure will hold the valve closed, but after the liquid inthe tank has been greatly reduced, there would not be enough pressurebehind the valve to hold it closed, and hence the necessity of providingthe spring 8.

The forward end of the spindle or rod 6 is formed with a disk 6 whichcontacts with the front end of the stuffing box, and the extremity ofthe rod 6 is also provided with the eye 10 through which passes a crossbar 11 pivotally connected at its ends to two rearwardly extending links12 located one on each side of the faucet body, these links beingoutwardly spread at their rear ends to conform to the contour of thefaucet body.

Formed upon the upper portion of the faucet body, preferably upon thepart 3,

is the rib 13 which forms a bearing or a' transverse pivot pin 14:. Themiddle of this bearing 13 is formed with the upwardly projectinginwardly beveled lug 15. Mounted upon the pivot pin let is thebifurcated lever 16, the two arms of which extend downward partiallyaround the faucet body on each slde and at their lower ends are cut awayand pivoted to the rear ends of the links 12. The upper end of the leverat its middle is formed with a cylindrical hub 17 slotted at its sides,as at 18, which slots extend into a socket 17 formed in the interior ofthe hub. This socket opens on the under face of the lever immediately inalinement with the locking lug 15. Mounted within the socket is theshiftable detent 19 formed at its lower end with the detent tooth 20which projects through the opening in the lower end of the socket and isadapted to engage with the upwardly projecting lug 15. A cross pin 21projects through the detent and passes through the slots 18 in'thesocket. A spring 22 is located within the socket and bears against theupper end of the detent, forcing it downward and yieldingly holding itin this position or in looking engagement with the lug 15.

As a means of raising the detent sufiiciently so as to clear the lug 15,I provide the cylindrical key 23 which at its upper end is provided witha cross bar or handle 2% and at its lower end is adapted to engage withthe detent and to lift the same.

It is to be understood that the spring 22 is of such strength that itwill hold the detent down into its locking engagement against allordinary efforts to press the spring, but the lower end of the key is soformed as to exert a wedging action upon the detent to raise it from itslocking engagement. To this end a key is provided upon its oppositesides with the inclined slots 25, these slots opening to the lower endof the key so that the wedge-like projection 26 is formed, which may beinserted beneath the cross bar or cross pin 21 to wedge the same upwardas the cylindrical key is rotated. The slots 25 are, of course, directedreverse to each other so that the rotation of a key in one directionwill raise both ends of the pin 21. upper edges of the projections 26form cam faces upon which the pins ride. The projecting end of thespindle 6 should, of course, be protected against any danger of breakageand to that end is so located as to be protected by the usual nose 27.It may be still further protected by forming a laterally projectingflange 28 beneath the nose 27 which shall extend out over the eye 10.The cylindrical hub is of such height and extends so far into the socketof the key that a good connection is formed between the key and leverfor the actuation of the latter.

The operation of my invention is evident from the drawing. Assuming thatthe valve is closed and that it is desired to open the valve, it is onlynecessary to apply the key 23 and rotate the same, whereupon the detentis raised from engagement with the locking lug and the lever 16 ispulled forward, forcing back the spindle and opening the valve againstthe force of the liquid in the reservoir and against the force of thespring 8. These parts may be locked in this position by withdrawing thekey, whereupon the spring 22 will force the detent down on the otherside of the locking lug and the valve will be held open until it isdesired to close same. lVhen the key is withdrawn, it is impossible toactuate the valve for the reason that the spring 22 is of such strengththat the detent can not be lifted without the aid of a key, and untillifted the detent locks the valves closed. It will be seen also that thekey forms a handle for operating the valve as well as for unlocking thedetent.

My invention is simple and easily constructed and thoroughly effectivein operation.

Having thus described the invention, what is claimed as new is:
